Upgrade in-tree OSS ICU header to 64.2 because macOS Mojave build will be dropped
Created attachment 439913 [details] Patch
Note https://bugs.webkit.org/show_bug.cgi?id=231085
Let's ensure it is built in EWS bots. It is possible that JSC test failure can happen just because ICU headers are upgraded, and some features are enabled.
